CARTRIDGE.

Application filed December 26, 1917.

To all whom it may concern:

Beit, known that I, Minn TELESZKY, a subject of the King of Hungary, residing at .lenners, in the county of Somerset and State of Pennsylvania. have invented certain new and useful Improvements in Cartridges, of which the following a specification.

The primary object of this invention is the provision ot? a cartridge having a projectile adapted for traveling through the water and provided with an automatically adjustable steering means for n'iaintaining the projectile in a straight course.

A turther object of the device is the pro vision of a projectile adapted to be fired into the water and arranged to be steered in a straight line of travel toward the. objective point at which the projectile is fired, the device being easy and inexpensive to manufacture and presenting the general form of a cartridge before being fired.

Vith these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described.

In the drawings forming a part of this application, and in which like reference characters refer to corresponding parts throughout the several views,

Figure l is a central longitudinal sectional view taken through the device.

Fig. 2 is a similar view of the bullet with its rudder positioned in operative arrangement.

Figs. 3 and 4: are transverse sectional views taken. upon lines IIIIII and IV -IV of Fig. 2 and Fig. is a detail sectional view of the rudder.

Referring more in detail to the drawings, the device includes a shell 10 having a' bullet 11 projecting therefrom while a iulminat-ing cap 12 is provided in the base or closed end 13 of the shell.

The bullet 11 is of tubular formation having an axial bore 14, a disk 15 bein seated within an annular socket 16 at the rear end of the bullet and thereby forming a check for the explosive material 17, such as dynamite arranged within theshell 10 between the end 13 thereof and the said bullet and disk.

It rubber 18 is normally arranged within the bore 14 having a rod 19 positioned Specification of Letters Patent. Pateilffid Sept. 10, 1918.

Serial No. 208.819.

axially ot' the bore and provided with a cross head 20 having its opposite ends slid ably positioned within opposite longitudinal grooves 21 in the sides of the bore 1%. The steering member or head 22 that is upon the end of the rod 19 opposite the cross piece 20, is provided with a plurality of radially projecting triangular shaped fins 23 thereby giving the appearance of the steering head somewhat the shape of a cone.

The projectile being adapted for firing in the water at submerged objects, it will be seen that upon exploding the charge 17, the bullet 11 and disk 15 will be projected forwardly into the water, and the force of the water passing through the bore l i will immediately remove the disk 15 from the socket 16 and will also rearwardly position the rudder 18 in its operative arrangement as indicatcd in Fig. 2 of the drawing. Shoulders 24 a re arranged at the rear ends of the grooves 21 forming stops against which the cross piece 20 of the rudder is seated at the extreme rearward movement of the rudder, thereby preventing the rudder from becoming separated from the bullet 11. The con tinued forward movement. of the bullet will be directed in a: straight course by means of the fins 23 of the rudder. It will be noted that the cross piece 20 is rectangular in cross section for maintaining the rod 19 in axial alinement with the bullet 11 during the rearward movement of the rudder as well as during the steering operation, the rudder being maintained within the bore 14 prior to the firing of the projectile by means of wax 25 arranged in the outer ends of the groove 21 if found desirable.

A cartridge is provided by which a bullet may be shot and steered in a straight course through the water, the bullet 11 having a tapered portion 26 terminating at the forward end of the bore 1 1 and presenting little obstruction to the passage of the bullet through the water.

hat I claim as new is 1. A cartridge comprising a shell, a bullet provided with an axial bore and a socket in its rear end normally positioned within the shell, a disk temporarily arranged within the socket, explosive material within the shell rcarwardly of said disk and bullet, the said bullet being arranged with opposite longitudinal grooves within the bore thereof, a rudder positioned within said bore before the device is fired including a cross piece slidably arranged within the said grooves, a rod carried by the cross piece and a finned steering head at the free end of the rod adapted for positioning rearwardly of the bullet in its operative arrangement after the firing of the device.

2. A cartridge comprising a shell, explosive material Within the shelha tubular bullet reinovably projecting into the shell seated against the said explosive and having a forwardly tapered end, the interior of the bullet being provided with opposite longitudinal grooves, a squared cross piece slidablyarranged Within the said grooves, re-

taining means in the outer ends of the grooves and stop shoulders at the inner ends thereof arranged Within the path of movement of the said cross piece, a rod carried by the cross piece and a head at the free end of the rod provided With a plurality of radially projecting fins of triangular formation, the said head being positioned rearwardly of the bullet during the passage of the latter through the water with the cross piece in contact with the said shoulders.

In testimony whereof I aflix my signature.
